BACKGROUND

This disclosure relates to an improved system for transporting anover-sized load.

Over the years, transporting over-sized loads has always been achallenge for heavy duty trailers. The issues encountered by heavy dutyvehicles in transporting over-sized cargoes rely on the safety standardsand/or regulations for public road transport set by the state or by acountry. Heavy equipment is often hauled and transported by heavy-dutytrailer through public roads, and over intercity routes that can coverseveral road types. In such case, different weight and size standardsmay apply as a trailer truck travels from one point to another.

Often, a standard platform trailer is used to accommodate oversizecargo. However, a standard platform trailer's usual load capacitytypically ranges from 50,000 lbs. to 80,000 lbs. Moreover, its lengthranges from 26 ft. up to 75 ft. Thus, larger or heavier lards may not beaccommodated and hauled using such trailer.

Another problem facing the transportation industry is having loads withbroad dimensions. For example, tall loads can present issues clearingunderneath bridges. This problem can sometimes be addressed if theoverall height of a heavy duty trailer is lower.

Another problem is that Further, the width of the wheelbase is alsosignificant for a heavy duty truck since wheelbase can allow or preventthe truck to pass through an area. Present trailers have a fixedwheelbase thus, limiting its usage in carrying only a cargo that has aspecific dimension and weight. Moreover, other heavy duty trailers canbe difficult to transport even when it does not carry any load becauseof the extended arms, which adds to the width of the vehicle.

Lastly, since large trailer would usually need to be transported throughnarrow roads and streets it is imperative that a steering mechanism isinstalled for better control of the vehicle specially through variouscurves. However, no present steering mechanism exists that function withthe trailer disclosed in this specification.

As such it would be useful to have an improved system for transportingan over-sized load.

FIG. 14C illustrates an embodiment of sliding plate 1100 wherein slidingplate 1100 mounts in the same positions regardless of its mountingdirection. In one embodiment, sliding plate 1100 can be mounted to swingarms 105 in two different directions. So that the vertical position ofdolly 104 does not change when plate is rotated, plate guides 1102 canbe placed parallel to each other, each an equal distance away fromsymmetry axis 1205. However, if two different vertical positions ofdolly 104 are desired, symmetry axis can be positioned closer to oneplate guide 1102 than the other.

By positioning a socket 1106 of plate guides 1102 such that it is(n*x)/2 away from a lateral line 1402 passing through symmetry axis1205, where n is any integer, and x is the distance between two adjacentsockets 1106 on plate guide 1102, plate guide 1102 will be positionableat the same set of discrete points, x distance from each other,regardless of the direction plate guide 1102 slides onto swing arm 105.In a preferred embodiment, n=−1, 0, or 1, and the reference socket 1106is a middle socket 1106. Further, to maintain a two-fastener connectionon plate guide 1102 comprising four sockets 1106, guide holes 603 onswing arm 105 can be spaced 2*x apart. For example, if x is 3 inches,sliding plate 1100, then sliding plate 1100 will be positionable atdiscrete points on swing arm 105, the discrete points three inchesapart. If sliding plate 1100 is removed from swing arm 105, rotated 180degrees, and repositioned on swing arm 105, it will be positionable atthe same discrete points. To maintain a two-fastener connection withplate guide 1102 in the example, guide holes 603 in swing arm 105 can beplaced six inches apart. Such configuration of plate guide 1102 in FIG.14C is beneficial because assembler of dolly-transport system 100 canassemble swing arm 105 and dolly 104 without considering the direct ofsliding plate 1100.

FIG. 14D illustrates an embodiment of sliding plate 1100 wherein slidingplate mounts in different positions depending on its mounting direction.In one embodiment, sliding plate 1100 can be mounted to swing arms 105in two different directions. By positioning sockets 1106 of plate guides1102 not on symmetry axis 1205 or an n*x/2 interval therefrom, plateguide 1102 will have a first set of positionable discrete points xdistance apart, and a second set of discrete points x distance apartsomewhere between the first set of points. Further, by positioning asocket 1106 of plate guides 1102 such that it is (n*x)/2+x/4 away from alateral line 1402 passing through symmetry axis 1205, the second set ofpositionable discrete points will be a set of points that are each acenter point between adjacent points with the first set of discretesets. Practically speaking, the combination of the first set of pointsand second set of points will yield a set of points equally spaced apartat a distance of x/2. Similar to the example in FIG. 14C, to maintain atwo-fastener connection on plate guide 1102 comprising four sockets1106, guide holes 603 on swing arm 105 can be spaced 2*x apart. Forexample, if x is three inches, then sliding plate 1100 will bepositionable at discrete points on swing arm 105 that are 1.5 inches.The set of points spaced 1.5 inches apart comprises a first set ofpoints spaced 3 inches apart, related to sliding plate 1100 mounted toswing arm 105 in one direction, and a second set of points related tosliding point rotated 180 degrees, spaced three inches apart, but eachof those points in the middle of adjacent points in the first set. Tomaintain a two-fastener connection with plate guide 1102 in thisexample, guide holes 603 in swing arm 105 can be placed six inchesapart, just as in FIG. 14C. Such configuration of plate guide 1205 inFIG. 14D is beneficial because assembler of dolly-transport system 100can have more precise control over the size of dolly-transport system100 with less holes drilled in swing arm 105.
